The Board of a Corporation and the Executive Committee of my Football Club, are both charged with the act of governing, both operate under a system for doing so (usually spelled out by a Constitution or Memorandum of Association or equivalent), and they're both a body of persons, just like the executive of a nation.
Therefore they satisfy the very dictionary definition of a government.
